It was great fun! Many thanks for organising it. It doesn't need to be official to provide a good laugh.

Though, the way we had it set up, I can easily imagine how it could turn into a line carnage if more than 4 kites start together... (especially in NW-SW winds with big gusts coming out of nowhere). If one guy gets overpowered, it requires some attention from all around to avoid him + his kite, not always easy at full speed.
If we were to have another go at it, I would suggest to make the triangle a bit bigger and a start line perpendicular to the wind direction (first bouy being dead upwind of the start line), that way it allows for everyone to start together with less speed and less risk of tangle + it gives some time until the first bouy to have some distance starting to appear between the faster and slower riders.
As far as I understand, this is the way most kite-racing are being done now days for that particular safety reason. They had another competition 10 days ago in Britany (France) with 100 riders all starting together!!! (some photos here:

I have some pictures of Saturday's session but unfortunatly none of racing... 'cause I was in the water most of the time

... will post them shortly.
see you and thanks again
